Benefits of technology
The present invention provides a lever switch that reduces the noise when the operating lever is moved in a stepwise manner. This invention prevents a big operating noise from being generated when the operating lever is operated in a stepwise manner.
Problems solved by technology
The switch moving body is usually urged toward the click feeling generator by an urging member such as a spring so as to reliably come into contact with the click feel generating surface of the click feeling generator, and therefore, when abutting against the trough portions in response to stepwise operation of the wiper switch, an end of the switch moving body is caused to collide with the bottoms of the respective trough portions by urging force, and hence a big operating noise may be generated upon each operation of the operating lever.

Embodiment Construction
[0013]An embodiment of the present invention will now be described in detail with reference to the drawings.
[0014]FIGS. 1A and 1B are perspective views schematically showing an appearance of a wiper switch which is a lever switch according to an embodiment of the present invention, in which FIG. 1A is a perspective view taken from the upper right, and FIG. 1B is a perspective view taken from the lower right.
[0015]Referring to FIGS. 1A and 1B, the lever switch 10 has a main body 11 which is a housing, and a lever body 12 which is rotatable relatively to the main body 11. The main body 11 is box-shaped and comprised mainly of a first case 13, a second case 14, and a third case 15. The lever body 12 is comprised mainly of an operating lever 16 and a switch moving body 17. The operating lever 16 is rotated by a user. In the following description, directions are defined using an XYZ coordinate system in FIGS. 1A and 1B.

A lever switch which is capable of preventing loud operating noise from being generated during stepwise operation of an operating lever. The lever switch has a case, a click feeling generator placed inside the case, and a switch moving body placed inside the case and rotated with respect to the case by operating the operating lever. The click feeling generator has trough portions that abut against a convex portion of the switch moving body. Click feelings are given by the convex portion of the switch moving body sequentially abutting against the trough portions in response to stepwise operations of the operating lever. The convex portion of the switch moving body is urged toward the click feeling generator. The click feeling generator and the case are placed away from each other with a space left between them in a direction in which the first case is urged.
Description
BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to a lever switch that is mounted on a vehicle, and in particular to a lever switch that is used as a wiper switch.Description of the Related Art[0002]A lever switch is known which is mounted on a vehicle and gives click feelings by causing a switch moving body, which rotates in response to operation of an operating lever, abutting against a click feel generating surface of a click feeling generator. When, for example, this type of lever switch is applied to a turn signal switch, a first driving body which is the switch moving body projecting from a base portion of the rotary operating lever is pressed against a cam member which is the click feeling generator disposed in opposed relation to the base portion, and when the first driving body abuts against a trough portion of the cam member, a click feeling is given (see, for example, Japanese Laid-open Patent Publication (Kokai) No. 2012-190796).[0003...
